<p>By default, this class requires that child nodes accepting drop are registered with <a href="output/Ext.dd.Registry.html" ext:cls="Ext.dd.Registry">Ext.dd.Registry</a>.
However a simpler way to allow a DropZone to manage any number of target elements is to configure the
DropZone with an implementation of <a href="output/Ext.dd.DropZone.html#Ext.dd.DropZone-getTargetFromEvent" ext:member="getTargetFromEvent" ext:cls="Ext.dd.DropZone">getTargetFromEvent</a> which interrogates the passed
mouse event to see if it has taken place within an element, or class of elements. This is easily done
by using the event's <a href="output/Ext.EventObject.html#Ext.EventObject-getTarget" ext:member="getTarget" ext:cls="Ext.EventObject">getTarget</a> method to identify a node based on a
<a href="output/Ext.DomQuery.html" ext:cls="Ext.DomQuery">Ext.DomQuery</a> selector.</p>
<p>Once the DropZone has detected through calling getTargetFromEvent, that the mouse is over
a drop target, that target is passed as the first parameter to <a href="output/Ext.dd.DropZone.html#Ext.dd.DropZone-onNodeEnter" ext:member="onNodeEnter" ext:cls="Ext.dd.DropZone">onNodeEnter</a>, <a href="output/Ext.dd.DropZone.html#Ext.dd.DropZone-onNodeOver" ext:member="onNodeOver" ext:cls="Ext.dd.DropZone">onNodeOver</a>,
<a href="output/Ext.dd.DropZone.html#Ext.dd.DropZone-onNodeOut" ext:member="onNodeOut" ext:cls="Ext.dd.DropZone">onNodeOut</a>, <a href="output/Ext.dd.DropZone.html#Ext.dd.DropZone-onNodeDrop" ext:member="onNodeDrop" ext:cls="Ext.dd.DropZone">onNodeDrop</a>. You may configure the instance of DropZone with implementations
of these methods to provide application-specific behaviour for these events to update both
application state, and UI state.</p>
<p>For example to make a GridPanel a cooperating target with the example illustrated in
<a href="output/Ext.dd.DragZone.html" ext:cls="Ext.dd.DragZone">DragZone</a>, the following technique might be used:</p><pre><code>myGridPanel.on(<em>'render'</em>, <b>function</b>() {
    myGridPanel.dropZone = <b>new</b> Ext.dd.DropZone(myGridPanel.getView().scroller, {

<i>//      If the mouse is over a grid row, <b>return</b> that node. This is</i>
<i>//      provided as the <em>"target"</em> parameter <b>in</b> all <em>"onNodeXXXX"</em> node event handling functions</i>
        getTargetFromEvent: <b>function</b>(e) {
            <b>return</b> e.getTarget(myGridPanel.getView().rowSelector);
        },

<i>//      On entry into a target node, highlight that node.</i>
        onNodeEnter : <b>function</b>(target, dd, e, data){ 
            Ext.fly(target).addClass(<em>'my-row-highlight-class'</em>);
        },

<i>//      On exit from a target node, unhighlight that node.</i>
        onNodeOut : <b>function</b>(target, dd, e, data){ 
            Ext.fly(target).removeClass(<em>'my-row-highlight-class'</em>);
        },

<i>//      While over a target node, <b>return</b> the <b>default</b> drop allowed class which</i>
<i>//      places a <em>"tick"</em> icon into the drag proxy.</i>
        onNodeOver : <b>function</b>(target, dd, e, data){ 
            <b>return</b> Ext.dd.DropZone.prototype.dropAllowed;
        },

<i>//      On node drop we can interrogate the target to find the underlying</i>
<i>//      application object that is the real target of the dragged data.</i>
<i>//      In this <b>case</b>, it is a Record <b>in</b> the GridPanel<em>'s Store.</i>
<i>//      We can use the data set up by the DragZone'</em>s getDragData method to read</i>
<i>//      any data we decided to attach <b>in</b> the DragZone<em>'s getDragData method.</i>
        onNodeDrop : <b>function</b>(target, dd, e, data){
            <b>var</b> rowIndex = myGridPanel.getView().findRowIndex(target);
            <b>var</b> r = myGridPanel.getStore().getAt(rowIndex);
            Ext.Msg.alert('</em>Drop gesture<em>', '</em>Dropped Record id <em>' + data.draggedRecord.id +
                '</em> on Record id <em>' + r.id);
            <b>return</b> true;
        }
    });
